RemarksOIV.Inventor.Gestures.Recognizers.SoDoubleTapGestureRecognizer analyses touch events and recognizes a one finger double-tap gesture. It returns an OIV.Inventor.Gestures.Events.SoDoubleTapGestureEvent with this gesture is recognized. The finger has to stay in a limitation area from the down event to the end one and must be completed within a maximum elapsed time. This recognizer only generates an END event.
Note:
In order to get touch events for the gesture recognizer(s) to recognize, the application must explicitly register a touch screen device (OIV.Inventor.Touch.Devices.SoWinTouchScreen, SoQtTouchScreen, etc).
In order to get gesture events, the application must explicitly register gesture recognizers with the touch screen device's touch manager (OIV.Inventor.Touch.SoTouchManager).
